Table 3.

The TaD subroutines for the topside reconstruction at a single point.

Input parameters Subroutine Output
Month, LT, glat, f10.7, Kp TSM: Topside Sounders Model Empirical functions of parameters

  • HT: topside scale height (≡HO+)

  • hT : transition height

  • RT: ratio HT/hT

Analytical functions based on Alouette, ISIS-1,-2 topside profiles (Bilitza 2001)
Hm, k, RT, hmF2, NmF2 and glat TSMP: Topside Sounders Model Profiler Empirical functions of parameters

  • HP: plasmaspheric scale height (≡HH+), HP = HT(9cos2glat + 4)

  • Ne: electron density profile in the topside ionosphere and plasmasphere

  • g is the ratio NH+/NO+ at hT

  • k is the correction parameter that converts Hm (the neutral scale height) to make it compliant with HT

Analytical functions based on ISIS-1 topside profiles to model plasmaspheric scale height
Digisonde parameters at the height of maximum density (hmF2, foF2, Hm), RT, and vTEC (GNSS) at the Digisonde location TSM-assisted Digisonde Profiler

  • where s = HHe+/kHm

  • The integral of the Ne profile can be adjusted to the measured vTEC by varying solely the correction parameter k

Calculation of the actual profile over each Digisonde location to update TSMP with current Digisonde and TEC (GNSS) parameters
